Addressing the problem of large-scale data mining, this is an interdisciplinary text that describes advances in the integration of three computer-science areas: intelligent (machine learning-based) data-mining techniques, relational databases, and parallel processing. The basic idea is to use concepts and techniques of the last two areas, particularly parallel processing, to speed up and scale up data-mining algorithms. The book is divided into three parts, the first of which presents a comprehensive review of intelligent data-mining techniques such as rule induction, instance-based learning, neural networks and genetic algorithms. Likewise, the second part offers a detailed review of parallel processing and parallel databases. Each of these parts includes an overview of commercially-available, state-of-the-art tools. The third part deals with the application of parallel processing to data mining. The emphasis is on finding generic, cost-effective solutions for realistic data volumes. Two parallel computational environments are discussed, the first excluding the use of commercial-strength DBMS and the second using parallel DBMS servers. It is assumed that readers have a knowledge roughly equivalent to a first degree (BSc) in accurate sciences, so that they are reasonably familiar with basic concepts of statistics and computer science. The book is intended primarily for industry-data miners and practitioners in general, who would like to apply intelligent data-mining techniques to large amounts of data. It is also suitable for academic researchers and postgraduate students, particularly database researchers, who are interested in advanced, intelligent database applications, and artificial-intelligence researchers interested in industrial, real-world applications of machine learning.
